Airfield & trip planning
PPR Explained: Getting It Right First Call
What to actually say when you call for PPR, what airfields want to hear, and the mistakes that get new pilots turned away.
Prior Permission Required (PPR) is not an administrative formality. In the UK, it is the primary mechanism aerodromes use to manage noise abatement covenants, runway turf conditions, livestock grazing, and apron parking capacity.
Arriving at a PPR-only airfield without permission can result in landing clearance refusal, administrative penalty surcharges, or a mandatory occurrence report.
Here is what UK aerodromes need when you make contact, the operational reasons behind the requirement, and a practical telephone and webform script.
The operational reasons behind PPR
Aerodromes enforce prior permission to manage five specific operational requirements:
Movement caps. Many rural aerodromes operate under Section 106 planning agreements with local councils that strictly cap visiting movements per day — exceed that number and the aerodrome risks planning enforcement, not just an annoyed ops desk.
Grass runway condition. Autumn and winter rain turns UK grass runways into waterlogged ground fast. Duty staff need to check the turf can take your aircraft's weight band before you commit to landing there.
Apron and bowser capacity. High-traffic GA aerodromes like Turweston or Sywell have finite hardstanding. PPR schedules arrivals so the apron doesn't gridlock on a busy Saturday.
Fire cover and staffing hours. Licensed aerodromes providing Rescue and Fire Fighting Services need an active duty crew present. Turning up outside published staffing hours without warning can mean no cover, and no clearance.
Information to have ready before calling
Have these seven details written on your flight log before calling the tower or submitting an online form:
- Aircraft Registration & Type: (e.g., "G-BODR, Piper PA-28-161 Warrior").
- Departure Aerodrome: (e.g., "Departing from Blackbushe EGLK").
- Estimated Time of Arrival (ETA): State in UTC / Zulu.
- Estimated Time of Departure (ETD): (e.g., "Departing at 14:00 Zulu").
- Persons on Board (POB): (e.g., "2 on board").
- Fuel or Services Required: (e.g., "Requesting 40L 100LL Avgas").
- Pilot Name & Contact Mobile Number: For urgent updates if the airfield closes due to weather.
Sourced contact methods across UK aerodromes
In the Airfield Atlas database, aerodromes specify different preferred contact channels:
| Airfield Name | ICAO | PPR Status | Preferred Contact Method | Contact Details / Notes |
|---|---|---|---|---|
| Cotswold / Kemble | EGBP | Required | Online form | cotswoldairport.com; phone +44 1285 771177 or ops@cotswoldairport.com |
| Turweston | EGBT | Required | Phone | 01280 705400 (Turweston Flight Centre); info@turwestonflight.com |
| Compton Abbas | EGHA | Required | Online form, phone fallback | Auto-PPR up to 5 days ahead online; same-day by phone 01747 811767 (option 1) |
| Popham | EGHP | Not required | Telephone (encouraged) | Not strictly PPR, but call 01256 397733 to check conditions before arrival |
| Netherthorpe | EGNF | Required | Telephone | Strictly by phone; quote your PPR number on first radio contact |
| Manchester Barton | EGCB | Required | Online form | egcbatis.co.uk/inboundppr; phone +44 161 789 1362 |
Practical telephone script: what to say
Airfield Ops: "Good morning, Turweston Operations."
Pilot: "Good morning. Requesting PPR for today, G-BODR, a Piper PA-28 inbound from Blackbushe."
Airfield Ops: "Go ahead with your timings for G-DR."
Pilot: "ETA 11:30 Zulu, two on board, ground stop for 90 minutes. We would also like 40 litres of 100LL."
Airfield Ops: "PPR is approved. Runway 27 is active, right-hand circuit, standard overhead join at 2,000 feet. Avoid Turweston village to the south. Settle fuel at the self-service bowser. Your reference is Alpha-Nine."
Pilot: "Copied, PPR Alpha-Nine, runway 27 right-hand, overhead join 2,000 feet, avoiding Turweston village. Thank you."
The exchange took 40 seconds, covered all legal requirements, and confirmed the noise-abatement restrictions.
PPR vs PPO vs PN
| Term | AIP Meaning | Operational Rule |
|---|---|---|
| PPR (Prior Permission Required) | Formal clearance required before departure from origin. | Do not start engine without confirmed PPR reference or approval. |
| PPO (Prior Permission Only) | Restricted to resident aircraft, based club members, or maintenance visits. | Public visits strictly by special arrangement. |
| PN (Prior Notice Required) | Notification of arrival required; explicit acknowledgement not mandatory unless contacted. | File flight notification or submit web form before flight. |
Consequences of omitting PPR
- Refusal of Landing: Aerodromes with active FISOs or ATC can refuse entry to the ATZ, forcing a diversion.
- Administrative Surcharges: Several UK aerodromes enforce published non-PPR surcharges ranging from £25 to £50 on top of standard landing fees.
- Safety Risks: Touching down on waterlogged grass can cause nosewheel collapse or runway excursions.
Always confirm PPR before engine start.
